First, let's estimate the dividend. The given final depth is -0.3675 km. Rounding it to the nearest hundredth, we get -0.37. Therefore, the estimate of the dividend is B. -0.37.
Next, let's estimate the divisor. The given rate is -0.015 km per minute. Rounding it to the nearest hundredth, we get -0.02. Therefore, the estimate of the divisor is A. -0.02.
Finally, let's divide the estimated dividend (-0.37) by the estimated divisor (-0.02) to find the estimate of the quotient.
-0.37 ÷ -0.02 = 18.5
Rounding it to the nearest tenth, we get 18.5. Therefore, the estimate of the quotient is C. 18.5.
Hence, the submarine took an estimated 18.5 minutes to reach its final depth.
